I’ve been doing it for the last 6 weeks I think. Has become normal now (it takes 4 weeks to form a habit?)
I do Mondays & Wednesdays. If I’m not riding the bike, I have an espresso for breakfast and maybe a berocca, if riding I’ll have a high5 Zero with the caffeine. Then I’ll have a soup & a banana for lunch about 12 and a soup for dinner about 7:30.
I find it reduces the amount I snack on non-fast days too.
Seems to be doing me good, but I don’t own any scales so I won’t be able to tell you how much weight I’ve lost.
I suspect I will swap to 6:1 during the party season…
